WPF Notes (2.2 DockPanel)--layout

After reading this section, I found that DockPanel is the dock property in the past WinForm. The original Dock property is a child control setting, and its parent level is not set. Now WPF instead abstracts a dockpanel at the father level and then sets the dock property of its controls.

<DockPanel LastChildFill="True">
　　　 <Button DockPanel.Dock="Left">Left</Button>
　　　 <Button DockPanel.Dock="Right">Right</Button>
　　　 <Button DockPanel.Dock="Top">Top</Button>
　　　 <Button DockPanel.Dock="Bottom">Bottom</Button>
　　　 <Button>Fill</Button>
</DockPanel>

DockPanel has a LastChildFill property that is generally set to true and is used for the last element, so the last element does not have to set the Dock property to automatically occupy all the remaining space. I tried, the LastChildFill property is not set, the default is true, and the XAML error is set to False.

Finally, the form level generally uses DockPanel to lay out the child modules on it. Relatively coarse, consider the problem of global view. such as toolbar,statusbar,navigation and so on.
